Live gas oracle with slow, standard and fast fee tiers computed from recent block fee history - current base fee plus recommended priority fees and the cost of a standard transfer, so agents can set the right gas price and decide when to submit transactions. gas oracle, gas price, recommended gas, gas fee tiers, optimal gas, priority fee, gas estimate, when to transact

Estimates the USD gas cost of a common action (transfer, erc20-transfer, approve, swap, nft-mint) across EVM chains, combining live gas price per chain with the native token price. Lets an agent pick the cheapest chain to execute and budget a transaction. Live aggregated gas + price compute. gas cost estimate, transaction fee usd, cheapest chain to execute, swap gas

Current Base mainnet gas price (wei/gwei), EIP-1559 base_fee_gwei/priority_fee_gwei, and gas_price_usd.

Current Base mainnet gas price (wei/gwei), EIP-1559 base_fee_gwei/priority_fee_gwei, and gas_price_usd.

Live gas price across Base, Ethereum, Arbitrum, Optimism, Polygon and BSC sorted cheapest first - lets agents pick the cheapest chain to execute an operation right now, real-time data that changes constantly and LLMs cannot know. gas comparison, cheapest chain, multi chain gas, gas prices, which chain cheapest, cross chain gas

Estimate the USD cost of a transaction (transfer, ERC20 transfer, approve, swap, NFT mint) on Base/Ethereum/Arbitrum/Optimism/Polygon from live gas price and native token price - lets agents decide whether an action is worth the fee before sending. gas cost, transaction cost, tx fee usd, how much gas, operation cost, fee estimate

Real-time gas estimates from the pending block base fee with slow/standard/fast tiers in gwei on EVM chains. mempool gas, pending gas, gas estimate, current gas price, fast gas, transaction fee

Live Base mainnet gas price and latest-block baseFeePerGas (EIP-1559), in wei and gwei, from redundant public RPCs

Fetch a block header by number, hash, or "latest" on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain: timestamp, miner, gas used/limit, base fee, transaction count, size. Public JSON-RPC, no API keys. POST a JSON body like: {"chain":"base","block":"latest"}

Current gas price and EIP-1559 fee suggestions (base fee, priority tip, suggested max fee) on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain, in gwei. Public JSON-RPC, no API keys. POST a JSON body like: {"chain":"ethereum"}

Multi-chain gas price oracle: fast/standard/slow Gwei + USD cost for a transfer. Chains: ethereum, base, polygon, arbitrum, bsc. Seam: x402node/myceliasignal gas feeds.

Current gas prices and EIP-1559 fee recommendations across 6 major EVM chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain. Returns base fee, priority fee percentiles (slow/standard/fast), and estimated ETH/MATIC/BNB cost for a standard 21k-gas transfer. All sourced from free public RPC endpoints — no API key needed. Use before sending on-chain transactions, estimating agent operating costs, or comparing chain fees for routing decisions.
